Subwoofer Editors Choice Award
(original review, May 2000) The VTF-2 departs from the familiar tubular, knit-wrapped appearance of Hsu subwoofers. Instead it's just a nice black block with a couple of holes in the side, but that's a big step forward for Hsu, which is not known for styling. What it is known for is deep-bass performance, and in its "maximum extension" mode the VTF-2 subwoofer blasted out an impressive 93-dB sound-pressure level (SPL) at a ground-rumbling 20 Hz and delivered an awesome average SPL of 107.1 dB. In its "maximum output" mode it put out 99 dB at 25 Hz and an average SPL of 109.7 dB.

I was impressed with the evenness of the sub's low-frequency output; its deep, powerful, tonally balanced presentation of stable bass images; its ability to produce floor-shaking bottom-octave rumble when program material called for it; and the enhanced sense of spaciousness and envelopment that it gave to well-recorded soundtracks and music (included in the price is a CD specially selected for its deep-bass content). Many subs costing four times as much as the VTF-2 would kill for this kind of performance.

Note: Tom's [1997] review sample had pre-production drivers with poor suspension alignment. The magnetic and mechanical centers were off by 5.5mm! Production units have this problem rectified, and should thus be capable of even higher SPL and lower distortion than his measurements indicate. If you want deeper bass extension, go for our other models that are aimed for precisely those people who want deeper bass.
